DAVID H. HARNLY, OF AUSTIN, ILLINOIS.

ADJUSTABLE WINDOW-SHADE.

To all whom it may concern:

Be it known that 1, DAVID H. HARNLY, a citizen of the United States, and resident of Austin, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Adjustable Window- Shades, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to window shades and more particularly to those which are so held as to be adjusted in position for use upon different portions of a window opening.

The object of the invention is to provide a window shade of the type described which shall be of simple and inexpensive construction and efficient in operation.

The invention is eXemplified in the structure to be hereinafter described which is illustrated in the accompanying drawings, wherein- Figure 1 is a front elevation showing a window frame and an adjustable window shade embodying the features of improvement provided by the invention mounted therein. Figs. 2, 3, and 1 are detail perspective views showing features of the window shade and its mounting. Fig. 5 is a central transverse sectional view of window shade. Fig. 6 is a detail front elevation of a holder for receiving the shade, some of the parts being shown in section, and Fig. 7 is a detail plan view of the parts shown in Fig. 6.

A window frame is shown at 10. The shade is indicated at 11. Preferably this shade is of usual construction, having a hem, 12, at its lower edge and being wound upon a roller, 13, having the usual winding spring, 14, and non-rotatable trunnions, 15. The usual filler stick, 16, is shown as being contained within the hem, 12, for expanding the same.

In order that the shade, 11, may be ad Specification of Letters Patent.

overturned end portion as 20, 21, constructed to receive one of the trunnions of the roller. To this end the part, 20, and the plate, 18, is provided with a slot, 22, for re ceiving the nonrotatable trunnion, 15, of the roller. The part, 21, of the plate, 19, is provided with a socket, 23, for receiving the usual rotatable trunnion, (not shown) of the roller. The plates, 18, 19, are adapted to be adjustably overlapped and are preferably held together in adjusted position by a clamp, 24:. To insure a rigid construction of the holder, 17, the plates, 18, 19, are each provided with an over-turned flange as 25, 26, extending along one edge. Preferably the two flanges 25, 26, are located at the opposite side of the two plates upon which they are respectively formed. By this means the two plates, 18 and 19 may be telescopically fitted together. The clamp, 24, is shown as being provided with oppositely facing hooked portions 27 and 28 adapted to embrace the upper and lower edges of the over lapped portion of the plates, 18, 19, and with a set screw, 29. The set screw, 29, has threaded engagement with a part of the clamp intermediate the hooked portions 27 and 28 and is adapted to bear against the adjacent plate, as 18, for holding the plates in adjusted position.

I have shown the roller, 13, provided with the usual gravity pawl, 30, for holding the roller against turning. The non-rotatable trunnion 15, is preferably provided with but a single notch, as 31, for cooperation with the pawl 30. In some instances it may be desirable to render the pawl, 30, inactive as by so positionin the non-rotatable trunnion, 15, as to bring the notch, 31, upon its lower side. hen this is done provision is preferably made for preventing the turning of the roller 13, when the shade, 11, has been completely wound thereon. As shown, the hooked portion, 28, of the clamp, 24, is provided with an integral lip, 32, adapted to extend into the path of the expanded hem, 12, of the shade, (Fig. If the clamp, 24, be constructed of sheet metal, as shown, the lip, 32, may be adjusted in position by permanently flexing the material from which it is made.

The holder, 17, and the shade, 11, mounted therein, are preferably hung upon a suitable cord as 33. To this end the parts 20 and 21 of the plates 18 and 19, respectively, are each formed with a bracket, 34, carrying a pulley, 35. The cord, 33, is extended about each of the pulleys, 35, and has its opposite ends wound upon a roller, as 36. The roller, 36, is preferably located in the upper part of the window frame as by being extended between the two sides of the frame in the usual manner of mount-ing the rollers for non-adjustable window shades. The two ends of the cord, 33, are each fixed to the roller, 36, as by being passed through a lug 37, mounted on the roller and knotted, as indicated at 38. As shown, the roller, 36, is of tubular metal construction now in common use as spring shade rollers, and having a longitudinal groove, 39, for receiving the upper edge of the shade. The lugs, 37, are each fixed upon the roller, 36, by being provided with an expanded base, 40, which is entered in the groove, 39, from one end of the same. A lug, 41, preferably of like construction as the lugs, 37, and fixed upon the roller, 36, in the same way, is provided intermediate the ends of the roller for connection with an operating cord, 42. A second operating cord, 43, is preferably attached to the lower edge of the shade, 11, in the usual manner. In some cases, as when the pawl, 30, is inoperative, a clamping roller, 44, will desirably be used for guiding the cord, 43, and holding it in adjusted position. As shown, the roller, 44, is of usual construction having spiral grooves 45, 46, of decreasing depth and extending in opposite directions from its midlength. This roller is conveniently mounted in a bracket, 47, secured upon the sill of the window frame. As shown, the bracket, 47 has a floor plate, 48. The front end portion of this floor plate is up turned, as indicated at 49, said up turned portion having oppositely inclined edges, 50 and 51, constructed to guide the cord, 43, toward the ends of the roller, 44.

The roller, 36, preferably has a non-rotatable trunnion, 52, at one end, and is provided with a gravity pawl, 53, which 006perates with a notch, 54 at the base of the trunnion, 52, for normally holding the roller, 36, against turning in a direction which would permit the holder, 17 to descend. In some instances, it is desirable to provide a spring for cushioning the descent of the holder, 17. To this end, the roller, 36, is provided with a spring, 55, of the form usually provided in spring shade rollers. By so adjusting the tension of the spring, 55, that it will not serve to lift the holder, 17, the shade, 11, may be held in any adjusted position by means of the pawl, 53, and when the holder, 17, is allowed to descend by releasing the pawl, its downward movement will be cushioned by the spring, 55. A spring shade roller of the construction now in common use for receiving non-adjustable window shades,'but' with its holding pawl reversed, may accordingly be used to serve as the roller, 36. When the holding pawl, 30, is rendered inoperative, as shown, and the cord 43 is held by the clamping roller, 44, the spring, 14, continually holds the shade, 11, under tension and prevents it from being displaced by air currents.

The entire construction may be mounted in place without doing other work upon a .window frame than is required for the mounting of a non-adjustable shade of ordinary construction. The location of the two rollers 35 at the opposite ends of the holder 17 and the use of a single cord 26 for supporting the holder, enables the roller 13 to assume a position perpendicular to the direc tion of draft upon the shade 11, during the operation of the shade, whereby the shade will always be centrally wound'upon the roller.

I claim as my invention-- l. The combination with a window shade and its roller, of a holder carrying the same, having cord receiving apertures adjacent its opposite ends, a second roller journaled in a fixed position, and a cord having its opposite ends wound upon the said last named roller and being slidably extended through both of the said apertures of the holder.

2. The combination with a windowshade and its roller, of a holder carrying the same, a spring roller journaled in a fixed position, a suspending cable connected to the holder and wound upon the spring roller in a direction to wind up its spring as the cable is drawn from the roller, a pawl normally acting to prevent the turning of the spring roller in said direction and an operating cord wound upon the spring roller for turning it in the opposite direction.

3. The combination with a window shade and its roller, of a holder carrying the same, a supporting roller journaled in a fixed position, a suspending cable connected to the holder and wound upon the supporting roller, a pawl normally acting to prevent the turning of the supporting roller in the direction to unwind the suspending cable therefrom, means for turning the supporting roller in the opposite direction and a spring acting on the supporting roller to retard the descent of the holder when the said pawl is released.

4. In combination with a window shade and its roller, of a holder carrying the same having cord-receiving apertures adjacent its opposite ends, a supporting roller journaled in a fixed position, a suspending cable having its opposite ends wound upon the said supporting roller and being slidably extended through both of the said apertures of the holder, a pawl normally acting to prevent the turning of the supporting roller in the direction to unwind the suspending cable therefrom, and an operating cord Wound upon the supporting roller for turning it in the opposite direction.

5. The combination with a Window shade and its roller, of a holder carrying the same having cord receiving apertures adjacent its opposite ends, a spring roller journaled in a fixed position, a suspending cable having its opposite ends Wound upon the said spring roller in the direction to Wind up its spring as the cable is drawn from the roller and being slidably extended through both of the said apertures of the holder, a awl normally acting to prevent the turning of the spring roller in the said direction, and an operating cord Wound upon the said spring roller for turning it in the opposite direction.
